Abstract: The glutathione S-transferase gene of Fasciola hepatica was amplified and its homology was analyzed. According to the published genomic sequence of Fh GST in GenBank, a pair of primers was designed and the open reading frame of GST gene of Fasciola hepatica was amplified by RT-PCR. The homology of GST gene was analyzed by molecular biological soft. The PCR analysis results showed that the Fh GST gene was 682 bp, and encoded 218 amino acid. It indicated that the Fh GST gene was highly homologous with Fasciola hepatica isolated from Australia, Fasciola gigantica and Paragonimus westermani. Because of the high homology of the GST gene of different parasite, it could not be used in diagnosis assay with Fh GST protein, but could be used in gene vaccine.The clone of Fh GST gene had advantages to investigate the function and effect of GST protein.

Key words: Fasciola hepatica; GST gene; sequence analysis
